or your thoughts. These are all ever changing. The "Real You" is your

awareness within that silently witnesses your body, mind, and emotions.
It has been present since before you could label things as good, bad,

Witness is your Real Self. Once in touch with it, you no longer identify
exclusively with your suffering body, thoughts, or feelings. There are a
